Historical forecast transparency
Your answer to: “Why did the forecast change?” Overlay historical forecast revisions on a commodity chart and see exactly what the market did, when it shifted, and what was known at the time. When the budget conversation gets uncomfortable, the supporting information is already there.
When the market moves, you need more than the final number
Procurement teams don’t just forecast costs. They defend them. To finance, to leadership, to the board. And when a commodity price lands somewhere different from where their forecast pointed six months ago, the question to procurement is never “what happened to the market?” It’s “why didn’t you see this coming?”
That’s not a forecasting problem, it’s a communication problem.
Historical forecast transparency gives you the transparency and context to answer that question clearly, every time.
See how forecasts evolved, not just where they landed
Every forecast revision Expana publishes is a snapshot of what the market looked like at that moment. Our historical forecast transparency lets you go back to any of those moments, overlay them on the current chart, and shows you precisely how the outlook shifted as new information came in.

The difference between accuracy and transparency
A single accuracy score can’t tell you whether a forecast missed because of an unprecedented supply shock, a policy change nobody saw coming, or something that simply hadn’t happened yet. Context can.
For teams that need to validate confidence in a forecast before committing to it, historical forecast transparency also serves as a practical back-testing tool — letting you look back at how previous projections held up against market reality, and understand the conditions under which they shifted.
Expana’s approach to forecasting has always been grounded in transparency: showing the assumptions, the rationale, and the driving factors behind every projection. Historical forecast transparency takes that further.
“Markets change. Forecasts should too. What matters is whether your team can clearly explain when a revision happened, what drove it, and what it means going forward.”
- Forecasting is dynamic and targets are recalibrated in response to market developments
